TORCH.

SPECIFICATION forming part of Letters Patent No. 718,598, dated January 20, 1903.

Application filed February 14, 1902. Serial No. 93,948. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES H. BROWN, a citizen of the United States, residing at Perry, in the county of Dallas and State of Iowa, have invented certain new and useful Improvements in Torches; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

The purpose of this invention is the provision of a torch which will be economical in the consumption of oil, obviate explosion, and allow for expansion of the oil when the reservoir is filled without waste,and which, further, allows for filling the reservoir Without the use of a funnel and without spilling.

For a full description of the invention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a torch embodying the invention. Fig. 2 is a vertical section thereof.

Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.

The torch comprises a reservoir and tube 2, the latter springing from a side of the reservoir and receiving the wick 3. The reservoir l is of frusto-conical form, and the tube2 communicates with the bottom portion thereof at one side. A handle 4 is applied to a side of the reservoir, preferably at a point diametrically opposite the tube 2, so as to be remote from the flame. The top of the reservoir has its central portion depressed, as shown at 5, and centrallyapertured to admit of supplying oil to the torch when required. A plug 6 closes the opening in the top of the reservoir and preferably has screw-thread connection therewith. A knob 7, forming a part of the plug, is made hollow and acts as a supplementary air-chamber to the air-space in the upper portion of the reservoir, and its provision is especially advantageous when the reservoir is filled and sudden expansion of the oil takes place, the oil rising Within said knob. This knob provides a grip when operating the plug, either to screw it home or remove it from the opening in the top of the reservoir. The depressed portion 5 of the top of the reservoir acts in the capacity of a funnel, and when the plug 6 is removed oil may be supplied to the torch by being poured into the depressed part 5 from a bottle or can, the oil finding its way to the opening in the top and passing into the reservoir without spilling. This depressed part 5 also subserves another useful purpose in that it provides an airspace 8 at the top of the reservoir surrounding the plug-closed opening, for a purpose presently to be explained. A vent-opening 9 communicates with the upper portion of the air-space 8 and admits air into the reservoir as the oil is consumed and also provides an outlet for air and gases, which may tend to produce dangerous internal pressure. When the reservoir is filled to the level of the under surface of the depressed part 5 and the plug 6 is in place, any expansion of the oil from any reason will cause the oil to enter the space 8, and the air thus displaced will escape through the vent 9.

Having thus described the invention, what is claimed as new is-- A torch centrally depressed at its upper end to form an air-space and provided with an opening at the lowest portion of the said depression, a hollow knob closing the opening and constituting a supplementary air-chamber, and a vent-opening communicating with the aforesaid air-space, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
